Research Philosophy

The focus of my research throughout my career has been on insect ecology and improving pest management through the implementation of IPM strategies in several cropping systems. My main research areas have included the biology, life history and natural enemies of my focal studied organisms.

Program Focus

My goal is to provide science-based solutions to implement IPM programs for the ornamental and turf grass industries in the Commonwealth of Virginia and beyond.

I am also interested in several research areas targeting pest management questions:

  • Pest population dynamics: using remote pest monitoring (automated pheromone traps) and remote sensing (hyperspectral signatures) to track pest densities
  • Conservational Biological Control: Use of insectary plants to promote beneficials
  • Augmentative Biological Control: Use of drones to release beneficials
  • Chemical Control: Finding alternatives to broad-spectrum insecticides


Current Research Projects

Monitoring the occurrence of the brown marmorated stink bug in the coastal area of Virginia (led by Julie Brindley)

Comparison of Amblyseius cucumeris and Orius insidiosus for biological control of Frankliniella occidentalis on greenhouse interspecific geraniums (led by Christopher Epes)

Phenology, forecasting and landscape ecology of the redheaded flea beetle in Virginia nurseries (led by Eleanor Lane)

Recruiting Graduate Students

I am actively looking for highly-motivated and hard-working students to be part of this team. If interested in applying, please send me an email at with your Resume. Let’s talk!

Extension Philosophy

When I think about Extension, I envision this connection between research and public good. The type of applied research conducted to answer practical questions asked from members of a community. To me, extension means sharing research information in face-to-face interactions with stakeholders at their operations. Extension is also a ‘two-way street’, where these interactions are invaluable experiences to researchers, since we learn from the stakeholders as well as provide to them with tangible science-based solutions for their specific needs. Trust is built from these interactions, where stakeholders openly communicate to us, the researchers; and we have accessible, encouraging and science-based responses addressing any inquiry or issue.

My biggest professional inspiration is seeing how science and research helps stakeholders to implement IPM strategies, under their specific settings and systems. I consider myself an ‘IPM facilitator’. I really enjoy being a ‘facilitator’ and connecting multiple research experts with stakeholder needs and vice versa, bringing the community concerns and needs to other researchers prioritizing topics and areas of interest in which they would like to conduct research.  Extensionists are facilitators by playing the vital role of informing stakeholders of the most relevant, up-to-date, available and effective options to address their needs.
